Three types of people will be the first to be judged on the Day of Judgment: an ostentatious fighter, an ostentatious learner, and an ostentatious charity-giver. Allah, the Almighty, will bring them and remind them of His favor upon them, which they will acknowledge. When asked about what they did with such a divine favor, they will say, respectively, that they fought, learned and taught, and gave charity for Allah's sake. The fact is that they did such things to show off, without intending them for Allah's sake. Therefore, they will be dragged on their faces and thrown in Hellfire.
